Representatives from the Faith & Freedom Coalition told msnbc, “We doubt this was done by any of our attendees, we strongly condemn these actions.

White House Senior Adviser Dan Pfeiffer responded on Twitter to Obama’s “appearance” at the conservative event.

The pro-family, conservative Christian group was established by Ralph Reed, former senior adviser for the George W. Bush and Dick Cheney campaigns. The organization, according to its website, is committed to educating and mobilizing people of faith to be effective citizens. Members strive to influence public policy and enact legislation that strengthens families and protects life and marriage.

The three-day gathering began Thursday and draws followers from the social conservative wing of the Republican Party and potential presidential candidates. New Jersey Gov. Chris Christie, one of the potential Republicans in the 2016 race, addressed the crowd Friday about overcoming drug addiction and expanding the definitions of abortion and education. Other speakers included Sens. Marco Rubio of Florida, Ted Cruz of Texas, and Rand Paul of Kentucky, as well as former Arkansas Gov. Mike Huckabee, Rep. Rick Santorum of Pennsylvania, and newly-elected House Majority Leader Kevin McCarthy.

The Republican leaders verbally attacked the Obama administration on a range of issues, including the crises in Iraq, Ukraine, and Syria, and for arming rebels in Syria.
